ELEC 255 Study Guide - Final Guide: Adjustable-Speed Drive, Motor Drive, Voltage Source
Document Summary
Lab assignment # 5: dc motor speed control, dc drives. To understand the speed control using the automationdirect gsd1 dc drive. To apply plc analog control over the dc motor speed. An adjustable speed drive is a device that controls speed, and direction of an ac or dc motor. Some high performance drives are able to run in torque regulation mode. The controls allow the operator to start, stop, and change direction and speed of the motor by turning potentiometers or other operator devices. These controls may be an integral part of the controller or may be remotely mounted. The dc motor converts power from the adjustable dc voltage source to rotating mechanical force. Motor shaft rotation and direction are proportional to the magnitude and polarity of the dc voltage applied to the motor. Speed pots can be replaced by 0 10v analog signals (plc, etc. ).
